A new two-story veterinary diagnostic laboratory of about 62,500 square feet, with parking, is proposed on a 152-acre site in East Marlborough Township. County records list it as an institutional project.
Public coverage points to the Penn Vet New Bolton Center campus near Kennett Square as the likely match. Its new $94 million laboratory is described as about 63,000 square feet and two stories. The sources do not name the township, so the match rests on size, type and location. The campus is a working veterinary hospital and farm, so the site is already institutional and agricultural.
The building would bring together two state-supported programs, one for animal diagnostics and one for equine toxicology, now spread across several buildings and leased space. Construction was reported as started in October 2026. Finish is expected in 2028, with move-in in 2029.
What it could mean nearby
- Construction traffic is likely through 2028 on the roads serving the campus, though the sources give no traffic study.
- The lab is meant to consolidate existing operations, so large job growth is not indicated in the sources.
- The project sits on an existing campus, so it does not appear to add homes or remove neighborhood open space.
Where it stands
News coverage reports that construction started in October 2026, so the main approvals appear to be in place, though no township approval record was found. Next steps are building construction, inspections, and occupancy by the lab programs.
